EEG-based classification of natural sounds reveals specialized responses to speech and music. MARA ("Multiple Artifact Rejection Algorithm") is an open-source EEGLAB plug-in which automatizes the process of hand-labeling independent components for artifact rejection. Participating in analyzing EEG data and comparing the neural activities under different conditions. Although a growing body of evidence has suggested that in some cognitive processes, the neural loci are largely lateralized to one hemisphere or the other, no existing work for EEG-based image classification tried to integrate this concept into the deep learning model to extract the region-level information from the brain data. We discuss our findings in more detail in the discussion. By Günter Edlinger, g.tec Medical Engineering GmbH and Christoph Guger, g.tec Medical Engineering GmbH.

NeuroI… Successful applications of brain-computer interface (BCI) approaches to motor imagery (MI) are still limited. classification performance, as well as results of our feature explainability analysis. This approach holds the underlying assumption that electrodes are equidistant analogous to pixels of an image and hence fails to explore/exploit the complex functional neural connectivity between different electrode sites. GitHub, GitLab or BitBucket URL: * . Every 250 rows of the dataset represented a time series repetition. The core of MARA is a supervised machine learning algorithm that learns from expert ratings of 1290 components by extracting six features from the spatial, the spectral and the temporal domain.
